Interval timer - Between

For the Between mode basically two timers are used: one to set the start of a
time window and a second to set the width of the time window. The second
trigger event must be within this time window.

The following sequence explains what happens:
1 The first trigger event starts interval timer 1.
2 A second trigger event occurs before interval timer 1 has expired, the timer
is reset.
3 A third trigger event occurs before interval timer 1 has expired, the timer
is reset.
4 Interval 1
5 Interval timer 1 expires and interval timer 2 is started.
6 Interval 2
7 Interval timer 2 expires while no trigger event occurred within the set
period. The complete trigger logic is reset.
8 The first new trigger event starts interval timer 1.
9 A second trigger event occurs before interval timer 1 has expired, the timer
is reset.
10 Interval timer 1 expires and interval timer 2 is started.
11 A trigger event occurs before interval timer 2 expires: a trigger is
generated.
